T 0 all whom it may concern:

Be it known that I, Harmon E. HowARD, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Belt Conveyers, of which the following is a full, clear, and exact description.

The invention relates to belt conveyers and more particularly to that type in which the belt is troughed to convey gram or sunllar material.

The objects of the invention are: to provide an improved construction in which the inclined troughing rolls are supported in brackets which are utilized to pivotally sup port the shaft for the horizontal rolls or pulleys so that any frictional binding on said shaft will be avoided; an improved construction in which supporting brackets at the inner ends of the troughing rolls are utllized to support the shaft for the horizontal rolls; an improved device for supportlnga troughing roll; and a simple and efficient construction for supporting the troughing and horizontal rolls.

The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Figure 1 is a transverse section of a trough-belt conveyer embodying the invention. Fig. 2 is a section taken through one of the supporting brackets and one of the troughing rolls. Fig. 3 is a detail section taken on line 3-3 of F1g. 2. Fig. 4 is a detail elevation of one of the pivoted bearings for the horizontal-shaft and its grease-connection. Fig. 5 is an lnner end view of one of the supporting brackets for a troughing roll, the shaft for the horizontal rolls being shown in section. Fig. 6 is an inner side view of one of the supporting brackets and Fig. 7 1s a plan of the same.

The improved conveyer comprises an endless belt 8, the lower reach of which is supported by pulleys 9 on a shaft 10 which is mounted in hangers 11 fixed on the girders 12. A beam 13 is supported upon the girders 12 to carry the guiding and supporting means for the upper reach of the belt. The upper reach of the belt is guided by horizontal rolls or pulleys 1 1 on a cross shaft 15 and upwardly and outwardly inclined on troughing rolls 16 at the sides of the belt respectively.

The combined mount or support for one of the troughing rolls 16 and one end of shaft 15 comprises a sectional bracket 17 in which ahollow shaft 18 for the troughingroll is rigidly sustained and in which a hearing 19 for one end of a shaft 15 is pivotally sustained. This bracket 17 consists of a pair of sections or members 20, each of which is secured to the girder 13 by a bolt 21. The lower portions of the sections 20 are secured together by a through-bolt 22 and the upper portions are secured together by a bolt 23 which passes through spaced lugs 24. Each bracket section 20 is provided with a curved portion 25 and the inner faces of these curved portions are provided with longitudinal ribs 26 which are adapted to engage and securely hold the lower or inner end of the shaft 18. This construction operates as a clamp for gripping shaft 18 and by employing the spaced lugs 21 and the ribs 26 an effective grip upon the hollow shaft 18 is attained. These portions 27 of the bracket-sections which are disposed inwardly of the curved portions 25 are spaced apart sufliciently to receive the shaft-bearing 19 between them. Each bearing 19 is formed with integral laterally projecting trunnions 30 which are adapted to rest in inwardly facing recesses 31 in the bracketsections 20. The upper ends of recesses 31 are open so the trunnions 30 can be removed from and dropped into recesses 31. The hub 32 of each troughing roll 16 is mounted to rotate on shaft 18 and a washer 33 between the lower or inner end of said hub and the clamp of the bracket 17 limits the inward and downward movement of the pulley. Shaft 18 is hollow and utilized for lubricant for the bearing-surface between the hub 32 and the shaft. A wooden plug 34 is held at the inner end of the hollow shaft 18 by a lug 35 which is integrally formed with one of the clamp sections 25 to retain the grease in the lower end of the shaft. A grease-cup 36 is secured to the outer end of shaft 18 by a set-screw 37. This cup is provided with a portion 38 which is adapted to lap over the end of the sleeve 18 to direct grease into said sleeve instead of into the space between the grease-cup and the shaft 30. A cap 39 of usual construction is used at the outer end of the cup to force the grease through openings to the bearing surfaces between the pulley and the shaft.

Each bearing 19 is provided with a lubricating device consisting of a pipe 41 extending downwardly from the bearing; an elbow42, and a grease cup 43 having its nipple 44 secured in the elbow and extend ing at right angles to the pipe 41. A cap 45 is adapted to force grease through the pipe 41 to the bearing surface between the shaft 15 and bearing l9.- The pipe 41, elbow 42 and nipple 44 form, in effect, an elbow between the sections of or Within the supporting bracket 17, so that the cap 45 will be accessibly disposed outside of the bracket.

The invention exemplifies an improved troughing belt conveyer in which the shaft for the horizontal rolls terminates adjacent the inner ends of the troughing rolls, so. that considerable saving in length of shaft is effected. Also one in which the troughing rolls and the horizontal rolls are disposed in the same transverse plane. Also one in which simple, inexpensive, and effective supporting devices are used for conjointly supporting the troughing rolls and the shaft for the horizontal rolls. Also one in which provision is made for convenient lubrication ofnthe horizontal shaft and the troughing ro s.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, Without departing from the spirit and scope of the invention.

Havin thus described the invention,

what I c aim as new and desire to secure by Letters Patent, is:

1. In a support for a conveyer-belt, the

naeeaee combination of a horizontal shaft, a roll on said shaft, troughing rolls, troughing roll shafts, supporting brackets in which the troughing roll shafts are supported, bearings for the horizontal shaft, and pivotal connections between said bearings and said brackets, said troughing roll and horizontal shafts being transversely alined;

2. In a support for a conveyer belt, the

combination of a bracket formed of sections,

a horizontal shaft, a bearing for said shaftseparate from and removably mounted in said bracket, a troughing roll and a shaft for supporting the troughing roll fixedly held in said bracket, the sections of the bracket being formed to support the bearing and fixedly secure the troughing roll shaft I between them.

3. In a support for a conveyor belt, the

combination of a bracket formed of sections,

a horizontal shaft, a bearingfor said shaft, a pivotal connection between the sections of the bracket and said bearing, a troughing roll and a shaft for supporting the troughing roll, mounted in said bracket, the sections of the bracket being formed to support formed of sections between which said bearing is disposed and provided with means for rigidly securing one end of the troughing roll shaft, means for securing the sections together and a pivotal connection between the horizontal shaft-bearing and the bracket.
